perf: drop libbpf const qualifier workaroundHEADmaster

Remove the bbappend that applied const qualifier fixes to libbpf.c.

The workaround was required for older kernel versions where building
perf with -Werror triggered warnings due to discarded const qualifiers
from strstr() and strchr().

The issue is resolved in the currently used linux-intel 6.18 kernel,
making this workaround no longer necessary.
